To all whom it may concern: ,l

Be' it known that I, Trmononn MEIXNER, a citizen oftheUnited States, residing at Winchester, in the State of Washington, have invented certain new'and useful Improvements in Pumps, of which the following is a specification.

This invention relates to improvements in pumps and embraces the construction of a' pump having an arrangement of piston chambers'and valves whereby the operating pistons will pump water onthe down and upward strokes thereof.

ne of the objects 0f the-invention is the construction of a simple pump having means whereby a plurality of pistons can be operated so that water will be pumped on the the pistons.

In the accompanying drawing Figure 1, illustrates a vertical sectional View of improved pump. Fig. 2, illustrates an enthe I lar-ged section of the gasket 27, showing one of the springs 20, 20.

Referring to the drawing, 1 denotes a piston chamber, which is connected with an inlet port -or pipe 2, which pipe is controlled by an inwardly opening flap or check valve 3, which valve is pivot-allysupported ate, and engages with an abutment or seat L1. In the piston chamber 1, a piston 5, carried by a piston `rod 16, operates. 6, extends slidably through a gasket 27, removably seatedin the wall 7, and through 8, and carries on its upper end a piston 9, operating in the cham- The upper end of the pipe'forming a pipe or chamber'lO, with the inlet port orpipe I flap valve 11, adapted to open in the same wayas the valve 3, and whichis arranged in similar manner. lThe lower end of the piston chamber 1', pipe 12,-to a discharge or lift pipe 13, connects by a lateral pipe 14, with the piston chamber 8, and with an inlet 15; The pipe 111-, is provided The piston rod l 2, and is provided with a check or with an outwardly opening check or iap vvalve 16, which is similarly arranged to the previously described valves, and the inlet 4port or pipe 15, is controlled'by a-check or flap valve 17, arranged as the other valves, but opening inwardly. The said gasket comprises a body portion 27, washers 26, an annular cap 25, a packing chamber 24, and a bushing 18, and issupported against the wall 7, through the agency of spring members. 19, 19, and 20, 20. The spring members 20, 20, are adapted to recede inwardly for the purpose of allowing the said gasket 427, to pass out' Vthe chamber 8' Patented Mar. 21 1911.-

when so desired, when the inwardly tapering washer 22, is drawn upwardly and contacts same, and the spring members 19, 19, are adapted to recede inwardly for the same purpose where they come in' contact with sides of pipe 8, as indicated by the numeral 23. An exhaust. port 21, is provided for the purpose of draining chamb gasket 27, is removed. A nut 28, is mounted on the piston rod (i, for the purpose of abutting against the bushing 18, of -the gasket 27, and forcing same -in position in the' ,wall 7.'

On the down stro-ke of the pistons 5, and 8, the valve 3, will open inwardly so as to allow water to be drawn into the piston chamber 1, and in the pipe 2, while 'the water which has on the rip-stroke of the pistons entered the pipe or port 15, and the chamber 8,' will be forced through the ipe 14, into the lift pipe 13, stroke the water that has filled the piston chamber- 1, and the'pipe 2, will be forced through said pipe en'd of the chamber 8, which pipe.

Having described my invention, that which I claim and desire to protect by Letters forms a lift is connected by a U-shaped Patent is,-
